AceShowbiz - Matthew Koma, the husband of Hilary Duff, proved that he's not just a supportive partner but also her staunchest defender. The 37-year-old musician delivered a fiery response to an internet troll who accused Duff of using Botox.

The controversy began when Duff, star of "How I Met Your Father" and former Disney Channel icon, posted a series of close-up selfies in a radiant yellow outfit on Instagram. While most fans praised her look, one detractor speculated about Botox, writing, "Why did she do Botox, I swear to god everyone else is the same."

Koma did not take kindly to this insinuation. In a swift and unapologetic comeback, he commented, "Get f***ed butterfly," referring to the troll's username.

This blunt defense of his wife earned him applause from Duff's fans, who admired his readiness to stand up for her. One fan commented, "Showing everyone how great husbands stick up for their wives."

Hilary Duff, who has been in the public eye since her teenage years as the star of "Lizzie McGuire," has faced ongoing scrutiny about her appearance. In a 2022 interview with Women's Health, she addressed the pressures women face to maintain their looks.

“We bust our a** to get our bodies in shape and to look the best we can... But I want to work on the inside. That's the most important part of the system," Duff revealed.

Despite the rumors and public scrutiny, Duff has never confirmed using Botox or any fillers. In fact, she emphasizes mental wellness as crucial as physical appearance. Recently, she shared her experience with a facial treatment called Aquagold on social media, which uses tiny gold needles to rejuvenate the skin.

Hilary Duff and Matthew Koma's relationship began in 2013 during the making of Duff's album "Breathe In. Breathe Out." They tied the knot in 2019 and are now proud parents of three daughters - Banks, Mae, and Townes. Duff also has a son, Luca, from a previous marriage.

Their story is a reminder of the importance of backing up loved ones amid public scrutiny, especially in the ever-judgmental world of social media.
